Title: Membrane bioreactor system for treating contaminated water from a cleaning system
Inventor: DOYEL KYLE J
IPC: B01D61/14
Filed: 1994-12-09
Abstract: The effectiveness of a system for biodegrading contaminated water obtained from washing articles with one or more organic cleaning agents which contribute from 100 to 100,000 COD of recalcitrant contaminants, depends upon an initial filtration using a reverse-osmosis ("RO") module. RO retentate obtained, containing the contaminants, is treated in an aerobic bioreactor. A stream of suspended biomass is withdrawn from the reactor and separated an ultrafiltration (UF) module, into a cell-free permeate, and a UF retentate without killing more than 25% of the living cells in the stream. The retentate is returned to the bioreactor. The bioreactor operates with a hydraulic retention time (HRT) of at least 24 hr and a solids retention time (SRT) of more than 50 days. A cleaning system including a wash water system and a rinse water system for electronic printed circuit boards is described.

Abstract: A fluid sensing pipette include an outer conductive tube forming a first electrode and an inner conductive tube forming a second electrode. The inner conductive tube is disposed concentrically within the outer conductive tube. To insulate the inner conductive tube from the outer conductive tube, the inner conductive tube is coated with a thin, uniform, and consistent polymeric coating. A hydrophobic polymeric tube is disposed concentrically within the inner conductive tube to prevent cross-contamination between different biological samples aspirated into the pipette. The inner and outer conductive tubes are separately coupled to a level detection circuit which permits the pipette to detect entry of the pipette into a conductive fluid. The level detection circuit determines the impedance between the first and second electrodes and produces a control signal in response to the impedance falling below a predetermined threshold.
Patent CA-2141395-A1 (CA)
Inventor: UJITA TOSHIHIKO
IPC: B41J2/175
Filed: 1995-01-30
Abstract: An ink container for storing ink and an ink jet apparatus having such an ink container is provided. The ink container has an ink tank providing an enclosed space within an inner wall of the tank. The ink container is filled with inner and outer porous members having open pores for holding ink. The inner porous members are disposed within the enclosed space so as to only contact and press against other inner or outer porous members or both. The outer porous members are disposed within the enclosed space so as to contact and press against the inner porous members and the inner wall of the ink tank. This arrangement of inner and outer porous members within the ink container prevents an uneven compression distribution which occurs when conventional porous members are inserted into ink containers or when ink containers containing such conventional porous members suffer impacts. Further, the porous members can fill the entire ink container regardless of the shape of its interior, thus reducing the amount of non-dischargeable ink and leakage.

IPC: C08K3/22
Filed: 1995-03-08
Abstract: EPM  and/or  EPDM  compositions  exhibiting superior green strength as compared to conventional EPM/EPDM compositions are attained by adding, along with the  rubber  curing  agents  and  various  conventional additives  as  desired,   colemanite  and/or  alumina trihydrate.  Colemanite, alumina trihydrate or a mixture of the two have unexpectedly been found to enhance the green strength of EPM/EPDM compositions prior to vulca-nization.  The green strength promoters of this inven-tion utilized in EPM/EPDM rubber compositions allows for faster mixing  (shorter mixing  cycles)  and  improved processing rates,  such as faster calender throughput rates, to be achieved.  The green strength promoters can be utilized in generally any type of EPM and/or EPDM rubber formulation to improve the green strength thereof without adversely effecting the other desired physical properties.  These green strength promoters are particu-larly useful in increasing the green strength of amor-phous (non-crystalline) EPM/EPDM compositions.

Filed: 1995-06-14
Abstract: A method of dyeing nylon, particularly cationic dyeable Type 6 and 66 nylon and light dyeable Type 66 nylon, so that the dyed fiber will resist taking on further dye and will have a high degree of wash and bleed fastness when the dyed fiber is subjected to a further high temperature aqueous dye bath. The method includes providing a bifunctional dye solution having a very low pH, i.e. no higher than 1.5. The dye is applied to the fiber with a degree of wet pick-up exceeding 100% by weight of the fiber. The fiber is then steamed, washed, and dried, and contacted by an alkaline solution, such as a trisodium phosphate solution. Thereafter, the fiber is autoclaved. Such a dyed nylon fiber can be combined with an undyed nylon fiber to produce a textile product. When such a product is subjected to a dyeing operation, to provide the undyed nylon with a color different from the color of the previously-dyed fiber, the previously-dyed fiber will not bleed or wash out, and will resist taking on the dye being used to color the undyed nylon.
